grahoot

this repo is no longer maintained. Moved to https://git.sr.ht/~fabiancodes/grahoot

installation

the cli client can be installed via the python package index:

pip install grahoot-py

or with automatically managed environments

pipx install grahoot-py

todo

• option not to use tls
• show live clock in client
• cleaner input handling in client
• make backend controlable through stdin/stdout

protocol quiz-client <-> server

All data is exchanged via the JSON format because it's easy to use in python. TLS will be used by default.

registration phase

client -> server:

{
    "username": "<username>",
    "game_pin": "<game_pin>"
}

server -> client:

{
    "status": "<0 when successful; 1 otherwise>",
    "message": "<descriptive message>"
}

server -> clients:

{
    "message": "registration end"
}

quiz phase

server -> clients:

{
    "title": "<title>",
    "time": "<time_in_seconds>",
    "points": "<points>",
    "type": "single choice" | "multiple choice" | "guess number" | "guess string",
    "options": [
        { "text": "<text>" },
        ...
    ], -- only used for single and multiple choice
    "solution": "Index <indicies of correct choices comma separated>" | "Guess <correct number>" -- if type is not "guess string",
    "solution": [
        { "text": "<possible solution>" },
        ...
    ], -- if type is "guess string"
    "rad": "<radius to get points in>" -- this entry exists only for number guesses
}

client -> server:

{
    "answer": "<answer>"
}

server -> clients:

{
    "solution": "<solution>",
    "score": "<new_user_score>"
}

end phase

server -> clients:

{
    "message": "end"
}

server control protocol via stdin/stdout (WIP)

This protocol gives the user the control over the server using it's stdin/stdout, which might be useful for remote control. For example, there could be a supervising process - acting as a server - responsible for multiple quizzes at once, giving the 'quiz master' the ability to start a quiz via a website or any other client.

controller will be C and server S

registration phase

S: <game_pin>
C: ok

foreach new_user:
    S: <new_user>
    C: ok

C: end
S: ok
S: <num of participants>
C: ok

If an ok is expected but something else is received, "error" will be written to stdout.

quiz phase

end phase
